I just checked the sitemap I installed a year ago and realised it has not been updated for a year!
In that time I have changed hosts and the generator folder had dissapeared, so I deleted the old sitemap and did a fresh install. All is working.
What I want to know is that does the sitemap.xml automatically update itself when a new link is added on the website or do I need to do something everytime a change is made?
In turn, does google/yahoo automatically crawl the sitemap after a change?
I have the configuration set up as:
Change frequency: Daily
